Fluid impelling device and electronic apparatus

Abstract

A new type of device, useful as a fan among other applications, in which fluid flow is induced by providing within the device a chamber of constantly increasing volume and a chamber of constantly decreasing volume. Fluid moves through these chambers impelled by the rotation of a pair of members linked together for rotation about skewed axes. The members move within a chamber having a spherical surface, into which open ports for inward and outward fluid flow. The device may be used to assist in cooling components of an electronic system such as a computer system.

Description

FIELD AND BACKGROUND OF INVENTION[0001]This invention relates to a fluid impelling device and to electronic apparatus.[0002]It is well known to induce a flow of a fluid such as a liquid or gas by employing a mechanical device which impels such flow. For fluids which are liquid, such devices are commonly known as pumps. For fluids which are gases, such as air, such devices are variously known as fans or compressors, depending in part on the degree to which the pressure of the gas is raised by operation of the device. Particularly as to devices which fall into the category of fans, two particular forms are in wide use: the radial blade fan and the scroll or squirrel cage fan.[0003]Radial blade fans are widely used to move air in homes, sometimes as overhead fans. As employed in smaller sizes to provide a flow of cooling air for devices such as electronic apparatus, such fans usually have a support for the rotating blade element which in is the form of a spider frame. Such spider frame...

Benefits of technology

"The patent describes a new device that helps to move fluid, like air, using a chamber that changes in size. This device can be used to cool computer components, for example. The device has two rotating parts that create a flow of air that can cool the components."

Problems solved by technology

The noise so generated has become problematical in electronic devices or systems intended for use in quiet locations such as a home or office.

That noise has been a problem with computer systems.

However, such fans deliver lower air flows from a greater volume of occupied space, and thus are a poor design choice for confined areas such as the housings of electronic systems.

Thus the class of fans has been little used and is generally deemed unacceptable in such applications.
